Real-time, in situ DNA hybridization detection with attomolar sensitivity without amplification using (pb(Mg1/3Nb2/3)O3)0.65-(PbTiO3)0.35 piezoelectric plate sensors.

Abstract

In this paper we have investigated real-time, in situ DNA hybridization detection using piezoelectric plate sensors (PEPSs) consisting of a highly piezoelectric lead magnesium niobate-lead titanate (PMN-PT) layer 8μm in thickness thinly coated with Cr/Au electrodes and electrically insulated with 3-mercaptopropyltrimethoxysilane (MPS) encapsulation.
